Anti-Histone H2A.X Antibody

Description

• General description: Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which approximately 146 bp of DNA is wrapped in repeating units, called nucleosomes. H2A.X, also known as H2AFX, is a variant of Histone H2A that is found in a subset of nucleosomes. H2A.X has a unique C-terminal tail that becomes phosphorylated following double-stranded DNA breaks following irradiation or apoptosis. H2AX is involved in DNA repair and the maintenance of genomic stability. It is been implicated both in homologous recombination and nonhomologous end joining DNA repair pathways. H2A.X is thought to have a critical function in the recruitment of DNA repair factors and DNA damage-signaling proteins. H2A.X is ubiquitinated by RING1 and RNF2/RING2 complex providing a specific mark for transcriptional repression. In addition, this protein can be ubiquitinated by the E2 ligase UBE2N and the E3 ligases RNF8 and RNF168 as result of double-stranded DNA breaks to recruit repair proteins at a damaged site.
